You can copy (or clone) an existing configuration file to create an all new guest. You must modify the name parameter of the guests' configuration file. The new, unique name then appears in the hypervisor and is viewable by the management utilities. You must generate an all new UUID as well by using the uuidgen command. Then for the vif entries you must define a unique MAC address for each guest (if you are copying a guest configuration from an existing guest, you can create a script to handle it). For the xen bridge information, if you move an existing guest configuration file to a new host, you must update the xenbr entry to match your local networking configuration. For the Device entries, you must modify the entries in the 'disk=' section to point to the correct guest image.

You must also modify these system configuration settings on your guest. You must modify the HOSTNAME entry of the /etc/sysconfig/network file to match the new guest's hostname.

You must modify the HWADDR address of the /etc/sysconfig/network-scripts/ifcfg-eth0 file to match the output from ifconfig eth0 file and if you use static IP addresses, you must modify the IPADDR entry.
